Our users are located in Active Directory with an LDAP path something like this:
CN=myusername,OU=User,OU=UnitedKingdom,DC=aaa,DC=bbb,DC=ccc
Using the OU=User,OU=UnitedKingdom,DC=aaa,DC=bbb,DC=ccc as the user search base we can set up the Authentication (https://rancher.com/docs/rancher/v2.x/en/admin-settings/authentication/ad/) And I have been able to get things working for UK people only….
However: There are multiple countries in which potential users of the cluster can come from E.G Germany, India etc… We have a lot of users organised in this way and so I wanted to get a unified view of them in the running rancher UI.
from the docs, User Search Base says
The Distinguished Name of the node in your directory tree from which
to start searching for user objects. All users must be descendants of
this base DN. For example: “ou=people,dc=acme,dc=com”.
So I cannot use either multiple search bases (AFAICS)
OU=User,OU=UnitedKingdom,DC=aaa,DC=bbb,DC=ccc
OU=User,OU=Germany,DC=aaa,DC=bbb,DC=ccc”,….
or wildcards to specify the users.
OU=User,OU=(*),DC=aaa,DC=bbb,DC=ccc
Q1) Is there a way to have multiple search bases or use wildcards, or is there a way round this that we can use?
As an alternative
Q2) could use NIS to authenticate. Is there a way to set up NIS as the source of users and groups?
If you change the Search Base to the root of your domain, it should find all users in your domain, rather than only users in one OU:
DC=aaa,DC=bbb,DC=ccc

So... this question is maybe not solely a programming question but I hope one of you can shed some light on my issue:
The base need we have in our software is to query the groups a user is associated too with
LDAP. For this task we actually use parts of LDAP Admin to query the user. Actually we want to query for the UserPrincipalName which at least to my knowledge is the most common way right?
So.. our problem is that the AD is setup such that the user has an UPN like foo#HUS
but the user actually is bound to the domain HUS.adomain.com (aka LDAP base: dc=HUS,dc=adomain,dc=com) and searching using an UPN like foo#HUS.adomain.com does not work - only foo#HUS works. So... the question is:
Is this common?
And is there a name/resource for that?
(sorry I'm quite new to that all...)
The goal would be to use as less parameters in the administration tool as possible
aka only the base (and form from the base the UPN username).
Update: I found at least one resource (in German) that states that this is possible but not recommended by Microsoft for Azure AD. (aka having a different mail address than UPN )
When you initiate a LDAP search using a UPN like foo#HUS.adomain.com it wont work because this value is not present in the userPrincipalName value. When you search for a user by building its UPN using all the domain suffix available in the forest, then you would not consider searching the userPrincipalName attribute.
It is very difficult to build every constructed attribute from base for querying because every Active directory environment would be different. As you have mentioned that you would like to build the attribute from base, it may work if this is the only AD infra that you are targeting. Every AD infra would have its own ways in which it will be setup.
However if you would want your tool to work in any AD environment you would have to consider some other parameters.
UPN is a editable attribute . An organization can set it up or can create a user without a UPN value. Below is example of user created programmatically by using old ADSI libraries. You can repro the same by removing any users userprincipalName attribute value and the user logon account name as shown in the pictures below.
UPN is an optional attribute and a user account can be present in AD without it as well. Coming back to your specific environment in this environment only foo#HUS works because "HUS" might be setup as a valid domain suffix within the Active directory. You can check this by opening the domain.msc console on any domain controller or a machine with Remote Server Administration Tools installed. You would find the UPN suffix as shown below . I changed it in my environment as shown below.
The value you will add will now show up in the . If you remove HUS from here for example any existing user who have user#HUS userPrincipalName populated will get removed because this is a optional constructed attribute in AD. And you will have to setup this for all the users in the environment . For example check below after I changed the username to dh # HUS .
The userprincipalName value also got populated with the same.
Hope this helps clarify your query and understand more on how to use the native Active directory tools to understand more while you develop your custom LDAP search functionality/tool.
I'm trying to build functionality into my app for 'admins' to assign users from their AD group to certain groups that are further assigned to app-specific roles. Basically a simple management component.
Adding the user with the oid to a group is easy, the problem I'm facing is finding the actual user.
Currently, the only option I'm seeing is making multiple api requests to v1.0/users (999 items max) and grouping them all in memory and then provide a simple search function to narrow it down.
I have also used the v1.0/me/people endpoint to search for users but this does not reveal all users from the AD group, just relevant users they deal with, so not too useful.
Is there any other api endpoint I could tap into to do a search ONLY on members of the same active directory?
Using the startsWith filter on multiple properties is probably the closest we can get to user search in MS Graph at the moment:
https://graph.microsoft.com/v1.0/users?$filter=startswith(displayName,'sarah') or startswith(givenName,'sarah') or startswith(surname,'sarah') or startswith(mail,'sarah') or startswith(userPrincipalName,'sarah')
Ended up switching to the old AD Graph API and implementing a query on the endpoint as follows:
https://graph.windows.net/{ tenant ID }/users?api-version=1.6&$select=mail,displayName,objectId,givenName,surname&$filter=startswith(givenName,'SEARCH TERM') or startswith(surname,'SEARCH TERM')
If a function receives 1 single param, it will search for that parameter in both givenName and surname but you could configure this to search accross any other supported fields.
You could also completely ditch the $select= completely to get the whole data. I didn't want the clutter though and those keys are enough for me.
Instead of going with startswith You may get better experience using search keyword:
https://learn.microsoft.com/en-us/graph/api/user-list?view=graph-rest-1.0&tabs=http#example-6-use-search-to-get-users-with-display-names-that-contain-the-letters-wa-including-a-count-of-returned-objects
We have an application where we store users login name in the format domain\username. We authenticate via windows and then get additional info from our database by matching the domain\username we get from the user to our database.
Now they want to move to the cloud. We authenticate users via apps in Azure AD. However, the user identifier we get back is first.last#domain.com.
I have fiddled around with https://graph.microsoft.com/v1.0/users/email and the select command to try and get the 'old' name. Howev,er I have not yet found out how to get it.
The reason they move to the cloud is that they are merging two ADs. So some users will be DomainA and some DomainB, but in the same tenant. So my first thought was to try and convert the mail to the other format. However, the two different ADs have different naming standards. One has DOMAINA\fila (two first letters from the first name and two first letters from the last name) and the other one has DOMAINB\firlas. Also it feels really ugly to try and solve it that way.
Is it possible to fetch the users loginname formatted as domain\username via Microsoft Graph?
Using the beta edition of Graph, you can obtain the user's domain and username from the onPremisesDomainName and onPremisesSamAccountName properties:
/beta/users?$select=userPrincipalName,onPremisesDomainName,onPremisesSamAccountName
The domain is stored as a FQDN so you'll need to do some translation. For example, domainName.ad.contoso.com might translate to domainName\).
This will give you a workaround so you can match up users with your internal databases. It is however only a temporary solution. Long-term, you really want to migrate to using the userPrincipalName. This is the primary user identifier and guaranteed to be unique within a given tenant.
Azure AD is a little different than the legacy Active Directory. Certain concepts from legacy AD such as Organizational Units (OUs), Group Policy Objects (GPOs), Kerberos Authentication, Lightweight Directory Access Protocol (LDAP), Domain trusts between multiple domains, and several others simply do not exist in the cloud.
So I'm just starting to play with CakePHP and was wondering if the following was possible:
A single install of Cake, with a super admin login. Then, admins that have access to specified "sub sites", and the ability to create/edit content and users on those sub sites. Finally, the ability to map domain names (not subdomains, but unique domains) to the routes; so instead of mysite.com/subsite/posts/1 it would just be newdomain.com/posts/1
Essentially, I'm looking to replicate the experience of using Wordpress Multi-user (with domain mapping).
Is this possible? If so, what should I be looking into?
Sure. You can even use the same set of code and just configure certain domains to point to the code. Then in the code base, tie a domain ID to each user and the content so it knows where it belongs. You can have admin users belong to all domains. Then when you add regular users, you can specify what domain they belong to.
You could establish the domain checking in the Config/bootstrap.php and then set the configuration for the domain like so:
Configure::write('domain_id', 'someDomainSpecificID');
Then you only have to maintain one set of code and one database from many domains.
If the domains have to be physically separate, you could set up one location for the ADMIN users (single database) and run everything against that.
There are many ways you could architect it, it just depends on what your specific needs are. It sounds like a cool project though.
I am trying to add a user to Active Directory through an MPS Web Service. I've been trying a long time to find the correct LDAP-url to use to tell it to add the new user to the Users group. I've tried things like:
LDAP://XXXX.YYY/OU=Users,DC=XXXX,DC=YYY
LDAP://XXXX.YYY/CN=Users,DC=XXXX,DC=YYY
LDAP://XXXX.YYY/DN=Users,DC=XXXX,DC=YYY
It seems the "farthest" I've gotten is an error that says I have given it an invalid Customer.
I really don't have a lot of experience with LDAP (pretty much none at all), so even just a good LDAP and Active Directory tutorial would be extremely useful (even that is eluding me right now). Thanks!
I've since lookup up the actual distinguished name in ADSI Edit, which was LDAP://XXXX.YYY/CN=Users,DC=XXXX,DC=YYY, but still have no luck.
You have error in your LDAP string.
Let's have examle:
user with account name User1 in organization unit Office1 where contoso.com is domain.
Object:
contoso.com/Users/Office1/User1
LDAP Path is:
LDAP://CN=User1,OU=Office1,OU=Users,DC=contoso,DC=com
Note that there is no slash in path itself
CN = Common Name
OU = Organizational Unit
DC = Domain Component
You can start with:

How Can I Get a List of All the Users Whose Passwords Never Expire?
if your domain is xxxx.yyyy.zzzz and you are search for all users; your path is:
LDAP://CN=Users,DC=xxxx,DC=yyyy,DC=zzzz
means every dot in domain replace with dc=
More directly, the default Users container (not a group) in a default Active Directory install would be CN=Users,dc=domain,dc=com
You are not clear if you are having trouble adding a user to a group, or if you are having trouble creating a user in a specific location.
